Abstract
The utility model relates to a butt joint with a circular top and a rectangular bottom. An upper port of the butt joint is circular while a lower port of the butt joint is rectangular, and planar combining plates and arc-shaped combining plates are respectively fittingly butted with one another and then are fixedly welded together to form the combined joint with the circular upper port and the rectangular lower port. The manufacturing technology for the special-shaped joint with the circular top and the rectangular bottom is implemented in a regular splicing and welding mode, the butt joint has the advantages of capability of realizing batch production and high manufacturing precision and efficiency, a manufacturing process can be simplified, and the butt joint is easy to machine and implement.
Description
Technical field
The utility model relates to the butt joint manufacturing technology of metal production industry, is specifically related to a kind of hemispherical dome butt joint.
Background technique
In metal manufacturing field, for satisfying the docking between distinct device or the pipeline, butt joint need to be processed into abnormally-structuredly, and abnormally-structured difficulty of processing is large, precision is difficult to control, causes manufacturing efficiency low and cost is higher.
Summary of the invention
The utility model provides a kind of hemispherical dome butt joint of gang welding structure for situation about existing in the prior art and problem.
Technological scheme: a kind of hemispherical dome butt joint, its upper end-hole is circular port and lower end mouth is rectangle hole, take the long limit AB in the both sides of cuboid mouth as the base, to grow limit central point O to the line of shortest length Duan Weigao of circular port marginal point C, isosceles triangle ABC is set as the plane combination sheet; Two long limits of rectangle hole respectively are provided with described plane combination sheet, and two minor faces of rectangle hole arrange the arc compounded plate to the remaining area between the circular port; Described plane combination sheet and arc compounded plate mate respectively and are welded and fixed that to form upper end-hole be circular port and lower end mouth is the built-up joint of rectangle hole after the docking together.
The long hem width degree of described rectangle hole is 2800mm, and the minor face width is 399mm.
The upper end-hole of butt joint is 1232mm to the height of lower end mouth.
The thickness of described plane combination sheet and arc compounded plate is 40mm.
Four drift angle arc transition of described rectangle hole, this knuckle radius is 70mm.
Beneficial effect: the utility model has been realized the manufacturing technology of the special-shaped connecting head of hemispherical dome by the assembly unit welding manner of rule, but has mass production, and accuracy of manufacturing is high, and the advantage that efficient is high, but simplified manufacturing technique are processed easily and implemented.
Description of drawings
Figure l is the Facad structure schematic representation of the utility model hemispherical dome butt joint;
Fig. 2 is the side structure schematic representation of Fig. 1;
Fig. 3 is the schematic top plan view of Fig. 1.
Among the figure, label 1 is circular port, and 2 is rectangle hole, and 3 is the arc compounded plate, and 4 is the plane combination sheet.
Embodiment
Embodiment one: referring to Fig. 1-Fig. 3, a kind of hemispherical dome butt joint, its upper end-hole be circular port 1 and lower end mouth be rectangle hole 2(up and down comparatively speaking).Mated respectively by plane combination sheet 4 and arc compounded plate 3 and to be welded and fixed that to form upper end-hole be circular port and lower end mouth is the built-up joint of rectangle hole after the docking together.
Wherein, the position of plane combination sheet 4 is: take the long limit AB in the both sides of cuboid mouth 2 as the base, to grow limit central point O to the line of shortest length Duan Weigao of circular port marginal point C, isosceles triangle ABC is set as the plane combination sheet.Two long limits of rectangle hole respectively are provided with described plane combination sheet 4.The position of arc compounded plate 3 is: the remaining area except both sides plane combination sheet 4 arranges the arc compounded plate, and namely two of rectangle hole minor faces are to the remaining area between the circular port.
The long hem width degree of described rectangle hole is 2800mm, and the minor face width is 399mm.The upper end-hole of butt joint is 1232mm to the height of lower end mouth.The thickness of described plane combination sheet and arc compounded plate is 40mm.Four drift angle arc transition of described rectangle hole.
